Health Checkup in Korea — The Complete Guide for International Visitors

Who it suits / what to tell us in advance

A comprehensive health checkup in Korea packs many tests into a single day and returns results quickly, so many visitors from Mongolia, Russia, Central Asia and China combine it with a trip.

• People who have to book each test on a separate date back home and want to check their health in one go
• People over 40 who have never had a stomach or colon endoscopy or an abdominal ultrasound
• People with a family history of cancer, heart disease or stroke who want to check early
• People planning a checkup for their parents, or as a couple or family

How is a Korean health checkup different?

Regular screening has long been part of the national system in Korea, so there are many centers dedicated solely to checkups, with well-planned patient flow.

• Many tests in one day: from blood draw to ultrasound and endoscopy, everything runs in sequence within one building.
• Sedated endoscopy is standard: you have the stomach and colon endoscopy while asleep, so there is little discomfort.
• Fast results: some results are explained by a doctor the same day, and the official report usually arrives within 1–3 weeks.
• Easy referral to specialists: if something is found, it is easy to continue to the relevant specialist the same day or the next day.

Basic vs. premium checkup — sample packages

Names and contents differ by center, but packages generally fall into the groups below. Items are added or removed to suit your age, sex and family history.

Do you really need a CT, MRI or PET-CT?

It is not about ‘the more the better’ — what matters is choosing the tests you actually need. CT and PET-CT involve radiation exposure, so as a rule they are recommended by a doctor after reviewing your risk factors.

From booking to the day before

1. 1
   Package consultation (2–4 weeks before departure): tell us your age, family history, medications and the tests you want, and your manager will match the center and package to you.
2. 2
   Pre-visit questionnairefill in your medical history, surgical history, allergies and medications. If you have test results from home, please send them too.
3. 3
   Diet adjustment (from 2–3 days before if you are having a colonoscopy): avoid high-fiber foods such as fruit with seeds, seaweed like gim and miyeok, mixed grains, and kkakdugi or kimchi.
4. 4
   Bowel prep solution (evening before + early morning of the day): drink it in divided doses at the times you are given, and drink plenty of water. You need easy access to a restroom at your accommodation.
5. 5
   Fasting (8 hours or more)have a light, early dinner the day before, and usually avoid food, gum and cigarettes after 9 p.m. Follow the center's instructions on whether water is allowed.

   Check-in (around 7–8 a.m.)your identity is verified with your passport and you change into a checkup gown. Your manager accompanies and interprets for you.
2. 2
   Basic testsbody measurements, blood pressure, vision and hearing, blood draw and urine test come first.
3. 3
   Imaging testschest X-ray, abdominal and thyroid ultrasound, ECG, echocardiogram and so on, in order.
4. 4
   Sedated endoscopyafter an injection in your arm, you sleep through the stomach endoscopy (about 5–10 minutes) and colonoscopy (about 20–30 minutes), then rest in the recovery room until you wake.
5. 5
   Meal and results consultationafter a light meal such as porridge, a doctor explains the results confirmed that day, depending on the center.
6. 6
   Heading back (usually between noon and 2 p.m.): the whole process takes about 4–6 hours, and if you had a sedated endoscopy it is best to rest at your accommodation.

If you take medication — check in advance

Do not stop any medication on your own; as a rule, follow the guidance of both the prescribing doctor and the checkup center.

Women's checkups — good to know

• Checkup items: add mammography and breast ultrasound, a Pap smear, pelvic (gynecological) ultrasound, thyroid ultrasound, bone density test, etc.
• Menstrual period: urine and cervical test results can be inaccurate, so it is best to schedule about 5–7 days after your period ends.
• Breast tests: Asian women often have dense breast tissue, so mammography and ultrasound are sometimes recommended together.
• Pregnancy and breastfeeding: X-ray, CT and some medications are restricted, so please be sure to tell us in advance.

Results, and what if something is found

• Checkup day
  At many centers a doctor explains some blood, ultrasound and endoscopy findings. Your manager interprets.
• 3–7 days
  If a biopsy was taken, results usually come around now. If you have already returned home, your manager will contact you.
• 1–3 weeks
  The official report is sent by email or post. Many centers offer English reports.
• After you receive the results
  Your manager summarizes the key points in your language and re-confirms any questions with the checkup center.

Depending on severity, findings lead to observation, follow-up tests at a hospital in your home country, or specialist care in Korea. If needed, we connect you with the relevant specialist, such as gastroenterology, cardiology or endocrinology, and if your schedule allows you can be seen during your stay.

Sample travel itinerary (2–4 days)

• Day 1
  Arrive and check in to your accommodation. If you are having an endoscopy, drink the bowel prep solution in the evening and rest. Your manager will go over the next day's schedule again.
• Day 2
  Morning checkup, 4–6 hours. After a sedated endoscopy, rest at your accommodation and have an easy-to-digest dinner.
• Day 3
  Results consultation, or specialist care if something is found. If you have free time, go shopping or sightseeing in Gangnam, Seoul.
• Day 4
  If no additional tests or care are needed, fly home. You can receive the official report after you return.

A basic checkup alone can be done in 1 night. Our partner checkup center is in the Gangnam area of Seoul (Seocho), so staying nearby makes the early-morning trip easier.

Questions to ask at your consultation

1. Which tests are essential for my age and family history, and which can I skip?
2. Is there a reason I need a CT or PET-CT?
3. If a polyp is seen during the endoscopy, is it removed on the spot?
4. Until when should I take my medication, and when should I stop?
5. Will a doctor explain the results on the day, and will an interpreter be with me?
6. When, in what language and by what method will I receive the official report?
7. If something is found, which department will I be referred to and how quickly?

How to choose a checkup center

• Dedicated checkup medical staff: check that endoscopy and ultrasound are performed directly by specialists in that field.
• Equipment and patient flow: look for tests that follow one another in a single building with short waiting times.
• Results explanation: check whether there is a same-day doctor consultation and whether reports come in English.
• Follow-up care: see whether there is a system for referral to specialist care or a university hospital if something is found.
• Support for foreigners: confirm language support such as an accompanying interpreter, medication name checks and result summaries.
